ELASTIC CUSHION-HEEL.

SPECIFICATION forming part of Letters Patent No. 766,711, dated August 2, 1904.

Application filed October 28, 1902. Serial No- 129,148. (No model.)

T 0 all whom, it may concern:

Be it known that I, JOHN F. B. LITCHFIELD, a citizen of the United States, residing at \Vorcester, in the State of Massachusetts, have invented a new and useful Improvement in Elastic Cushion-Heels, of which the following is a specification.

The object of my invention is to provide a complete cushion-heel composed of a combination of rubber and leather. lifts adapted for attachment to the sole of a boot or shoe at one operation; and it consists in combining an in ner rubber lift and outer leather lifting with an attaching-nail and a fastening means provided with one or more spurs and a perforated base, through which the attaching-nail is loosely passed, the head of the nail being so arranged relatively to the leather lifting that upon the driving of the heel upon the sole the compression of the rubber lift will allow the leather lifting to serve as a means for driving the nail, and at the sametime the resilience of the rubber lifting will cause the removal of the leather lift from the head of the nail, so as to allow for the required yielding movement after the heel has been attached to the sole.

In the accompanying drawings, Figure 1 represents the top view of an elastic cushionheel provided with my improvement. Fig. 2 represents a side view of the same. Fig. 3 represents a section taken in the line 3 3 of Fig. 1. Fig. L represents a section as in Fig. 3, showing the attachment of the heel to the sole of the shoe. Fig. 5 represents an enlarged side view of one portion of the fastening device, the same being provided with a single attaching-spur. Fig. 6 represents an under view of the same, showing an end view of the attaching-spur. Fig. 7 represents an under view of the same when provided with a plurality of attaching-spurs. Fig. 8 represents a section taken in the line 8 8 of Fig. 6. Fig. 9 represents an enlarged side view of the driving-nail, which serves to form the other portion of the fastening device. Fig. 10 represents an axial section showing the parts of the fastening device arranged in connection with each other.

In the drawings, A represents an elastic heel-lift, made of rubber or other suitable material, and B the outer lifting of the cushionheel.

O represents the inclosed fastening device, made in two parts a and b, the former consisting of a base plate or head 0, provided with a perforation (Z and with a projecting spur c, and the latter of a driving-nail provided with a headf and having its shank portion 9 loosely fitting the perforation (i! of the part a.

The part a of the fastening device is preferably secured to the rubber tip A in the process ofvulcanizationandembedded therein, as shown in Fig. 3, and the projecting spur c of the fastening device is to be driven into the lifting B, which serves to form the outer portion of the cushion-heel, and upon the proper attachment of the lifting B the heel will he completed, as shown in Fig. 2, ready for attachment to the sole of the boot or shoe at one operation by means of asuitable press. The connecting-base c of the part a of the fastening device is embedded into the rubber lift A far enough to provide a recess h in the said lift, whereby a vacant space Jmay be formed between the head f of the drivingnail 7) and the surface j of the outer lifting, the said recess being made of such depth that when the heel is placed under pressure for the attachment of the heel to the sole of the shoe the elastic lift will be so compressed that the surface of the outer lifting will be caused to bear upon the head of the drivingnail 7) of the fastening device and that the resiliency of the elastic lift will upon the relief of the head of the driving-nail b from pressure cause the removal of the outer lifting B from contact with the head of the drivingnail, so as to form a vacant space '1', which will allow for the required sliding movement of the parts a and b when the heel is in use.

The attachment of the cushion-heel to the sole E of the shoe is represented in Fig. 4., the end Z of the driving-nail 6 being clenched against the inner surface I of the solo. The part a of the fastening device may be provided with a plurality of spurs v, as shown in Fig. 7, instead of the single spur shown in Fig. 5 for attaching the outer lifting B to the rubber lift A.

an elastic lift provided with a recess for the a head of the attaching-nail, and the fastening means provided with one or morev drivingspurs and a perforated base, with the attaching-nail held in the perforated base of the attaching means and adapted for limited sliding movement therein, and the outer lifting secured to the elastic. lift by the driven spur of the fastening means, and adapted for action upon the head of the attaching-nail when the heel is being attached to the sole, and removed from the head of the nail by the resilience of the rubber lift, after the heel has been attached, substantially as described.
